H0.Certainly, H1, H2 can also be respectively greater than H0, it is preferable that H0 ＜ H1≤1.5H0, H0 ＜ H2≤1.5H0, but not limited to this；
Alternatively, H1, H2 can also be slightly less than H0, for example, H1, H2 and H0 meet：0.8H0≤H1 ＜ H0,0.8H0≤H2 ＜ H0, at this time
The difference of H1, H2 and H0 are respectively within the scope of one of very little.It is appreciated that the concrete numerical value of H1, H2 can be according to being actually subjected to
It asks and adaptive change, the present invention is not particularly limited this.
Wherein, stator slot includes different the first stator slot 141 and the second stator slot 142 of flute profile, at this time the first stator slot
141 is different with the cross-sectional shape of the second stator slot 142.Specifically, for example, as Figure 1-Figure 5, the side with yoke portion 11
Opposite is the first stator slot 141 (for example, stator slot of left and right two in Fig. 1-Fig. 5), the inner wall of first stator slot 141 with
Minimum range between the periphery wall in corresponding yoke portion 11 is H2, four additional stator slot is respectively adjacent to four angles in yoke portion 11,
This four stator slots be the second stator slot 142, the inner wall of second stator slot 142 and the inner wall of corresponding mounting-positioning holes 13 it
Between minimum range be H1, in order to ensure that H1, H2 are equal or slightly larger than H0, two the first stator slots 141 court from inside to outside respectively
Extend to the side in corresponding yoke portion 11, radial line of first stator slot 141 preferably along stator core 1 is symmetrical, and four second fixed
The direction that pilot trench 142 is respectively facing corresponding mounting-positioning holes 13 extends.Here, it should be noted that direction "inner" can manage
Solution is, towards the direction at 1 center of stator core, opposite direction is defined as "outside", the i.e. direction far from 1 center of stator core.
Enameled wire is wrapped in across multiple stator slots on multiple stator tooths 12.Optionally, enameled wire is aluminium enamel-covered wire or copper
Enameled wire.As a result, under the premise of meeting stator requirement, the groove area of stator slot is increased, it is larger so as to use line footpath instead
Enameled wire such as aluminium enamel-covered wire, copper loss is constant (or reduce), ensures that electric efficiency is constant (or promotion), reduce motor at
This.In addition, the weight of motor is mitigated, transportation cost declines, and the overall cost of motor further decreases.
Optionally, the internal face of stator slot is formed as the combination of plane, cambered surface or plane and cambered surface.Here " stator slot
Internal face " refer to stator slot neighbouring yoke portion 11 periphery wall a side surface, such as the example in Fig. 1, Fig. 3-Fig. 6
In, the internal face of the first stator slot 141 is formed as cambered surface, and the internal face of the second stator slot 142 is the combination of two planes.Scheming
In 2 example, the internal face of the first stator slot 141 is the combination of three planes, and the internal face of the second stator slot 142 is two flat
The combination in face.It is appreciated that the concrete shape of the internal face of stator slot can be processed into arbitrary shape, this hair according to actual requirement
It is bright that this is not particularly limited.
Stator according to the ... of the embodiment of the present invention by the way that H1, H2 are set as suitable with H0 sizes, and sets stator slot to
Including flute profile different the first stator slot 141 and the second stator slot 142, the effective area of stator slot is increased.When stator application
When on motor, may be used the larger aluminium enamel-covered wire of line footpath, keep motor phase resistance constant (or reduction), copper loss it is constant (or
Reduce), electric efficiency is constant (or promotion), and motor cost reduces, while the weight of motor is mitigated, and reduces transportation cost,
The overall cost of motor further decreases.
An alternative embodiment according to the present invention, each stator tooth 12 include the first tooth being sequentially connected from inside to outside
121 and second tooth 122, the second tooth 122 be connected to the outer end of the first tooth 121, the first tooth 121 is configured to the interior of the first tooth 121
The thickness at end is less than or greater than the thickness of the outer end of the first tooth 121.For example, as shown in figure 3, the first tooth 121 is configured to from interior
Be gradually reduced to outer thickness, the thickness of the second tooth 122 is remained unchanged along inward-outward direction, at this time the second tooth 122 in yoke portion 11
Two side walls in circumferential direction are parallel to each other.Certainly, the first tooth 121 may be configured as thickness from inside to outside and gradually increase, such as
Shown in Fig. 4.
Alternatively, the extending direction phase of the extending direction of the two side walls of the second tooth 122 and the two side walls of the first tooth 121
Together, as shown in figure 5, the first tooth 121 is configured to thickness from inside to outside gradually increases, correspondingly, the second tooth 122 is also configured to
